United States. 1993. The Bonneville Power Administration. Department of Energy. Revision 3—65 p. A handbook was compiled to help industry identify opportunities for cost-effective application of these motors. It covers the economic and operational factors to be considered when motor purchase decisions are being made. Its audience includes plant managers, plant engineers, and others interested in energy management or preventative maintenance programs. The Handbook contains a discussion on the characteristics, economics, and benefits of standard versus high-efficiency motors in the 1 to 200 horsepower range. Handbook contains guidelines to help you identify motors that are candidates for replacement with energy-efficient electric motors. Using readily available information such as motor nameplate capacity, operating hours, and electricity price you can quickly determine the simple payback that would result from selecting and operating an energy-efficient motor.A motor performance database is supplied for use in identifying, evaluating, and purchasing energy-efficient motors and includes information on full and part load nominal efficiency and power factor as well as material on specific models and costs. Descriptions of how operating factors such as speed and design voltage effect performance are included. Typical operating conditions are also covered. Steps are outlined for launching a motor improvement program, which includes a worksheet to determine potential energy savings and the economic feasibility of an energy-efficient motor project.
